Madisound was established in 1972, and we accumulated an enormous library of raw loudspeaker driver specification sheets. In 201,7, we created the Madisound PDF Library to collect these PDFs in one easy-to-search location.

In addition to loudspeaker driver specification sheets, we are uploading PDFs of publications by and about speaker brands, cabinet enclosure plans, and free passive crossover designs.

We are here to help you.
